Restep is an add-on board for Recore A6 which gives it an extra TMC2209 stepper driver. This is great if you want to build a 3D-printer with 7 motors, like the Voron 2.4.
Mounting it on Recore
Restep should be mounted so the stepper is pointing upwards and the 6 pin header is pointing down. The 6 pin female header goes into the header on the board marked S6 or S7.
If you only have one Restep board mounted on Recore, you do not have to alter it in any way. The default UART address will then be 3. If you want to add one more board, you can cut the lines on AD0 which will give the board address 2. Address 0 and 1 are reserved for stepper 4 and 5 which are mounted on the board on UART3(pins PD0/PD1).
In this example, the X-axis is routed to S7. Only the relevant changes are shown.
